Help extending the ride plate

[z00m]

So i understand extending the ride plate will stop my hurricane Porpoising , so how much should i extend it to , has any one got a drawing or pic i can work from, I have access to thick alloy plate and can get the extention welded on , so will it help and how should i make it,

Not sure on a Hurricane, but my SL extended plates are around 15 inches give or take depending on manufacturer. Shape and depressions all have some affect on ride characterisitcs. Maybe try matching the stock plate's lines. Also have you mounted sponsons on the boat? Those help alot more for porpoising than a ride plate extension would.

Stop porpoising NO! not from what I hear, but it will be better than it is now.

Ah yes, Wetwolf runs sea-doo HX sponsons on his Hurricane. I just got mine running and plan to get some more seat time on it before doing any mods. The ride is quite different compared to my SL & SLX.

So where is the best place to fit sponsons. i see wetwolf has them high , my cane use to have them lower , then one fell off so i removed the other, also what is the best way of fixing them to the hull so they dont pull off, cant see how wetwolfs would combat porpoising so high up
I will be extending my ride plate monday

My ride plate mod

looks a mess and the only part on the ski that had not been refurbished,



paint stripped and cleaned



Light gauge temp made so all the profiles look right,



think i will roll the outer edges to follow the ride plate rather than put straight bends as with wetwolfs,



The proper plate will be welded on monday out of 6mm aluminium
